Question

Find the zeroes of
$\sqrt{2} x^{2} + 7x + 5 \sqrt{2}$
​

Answer 1

Step-by-step explanation:

$\sqrt{ {2x}^{2} } + 2x + 5x + 5 \sqrt{2}$

$\sqrt{2} x(x + \sqrt{2} ) + 5(x + \sqrt{2} )$

$(x + \sqrt{2} )( \sqrt{2} x + 5)$

$x = - \sqrt{2} \: and \: \frac{ - 5}{ \sqrt{2} }$

Answer 2

Answer:

$- \sqrt{2} \: \: \: \: and \: \: \: \: \: \: \: - \frac{5}{ \sqrt{2} }$
